Couldn't anyone who has Windows test this program to see if fixes the
problem (or part of it)?
It could be a start point for a solution.
What problem(s) do you expect this to solve?
What that program does is simply give you a way of sending a file with
PostScript commands to a printer that supports PostScript. So if a
user has a PostScript capable printer, but cannot refer to that
printer either as a port such as LPT2 or as a networked share such as
\\server\printer, then yes, such a user will be able to use that
program as a solution.
